Answer:
5. X = 2, Y = 3
6. X = 3, Y = 8
Step-by-step explanation:
For 5, it is easier to use the substitution method to solve. Plug the Y equation into the Y value of the first equation and simplify.
-3x - 2(5x-7) = -12
-3x - 10x + 14 = -12
-13 = -26x
x = 2
Then, plug the X value into either equation.
y = 5(2) -7
y = 3
For 6, it is easier to use the elimination method to solve. Multiply the first equation by 2 in order to eliminate 4y.
10x - 4y = -2
x + 4y = 35
Add these equations and simplify.
11x = 33
x = 3
Then, plug the X value into either equation.
3 + 4y = 35
32 = 4y
y = 8

Three boys (Dmitri, Ken, and Adam) have three different favorite colors (red,green, and blue)
• Dmitri does not like red
• Adam does not like red.
A. Dmitri's favorite color is blue.
B. No one likes green
C. Ken's, favorite color is red
D. Ken's favorite color is not red.
Answers
========================================================
Explanation:
We're told that Dmitri and Adam do not like red. So that must mean that Ken likes red. This immediately leads to choice C as the answer. This is assuming that each boy picks one of the three colors (and no colors can be repeated).
----------------
Extra info:
Choice A is false because we're not sure if Dmitri likes blue or green. We don't have enough info. Choice B is false because someone has to pick green. There are three boys and three colors. Again I'm assuming each person picks one color and the colors aren't repeated.Choice D is false because it contradicts choice C.

We can first multiply both sides by p.

Answer:
m∠1 = 130°
m∠2 = 158°
Step-by-step explanation:
For the given figure, we have;
The measure of angle m∠1 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;
m∠1 = 99° + 31° = 130°
m∠1 = 130°
Similarly, the measure of angle m∠2 is given by the exterior angle theorem as the sum of the two opposite interior angles as follows;
m∠2 = 28° + m∠1 = 28° + 130° = 158°
m∠2 = 158°.

Answer:
25% or 1/4
Step-by-step explanation:
The probability of all correct is [tex]\frac{1}{4}[/tex] or 25%.
Given that,
There are 3 questions given i,e a =3. Each question had four choices i.e b = 4.We need to find the probability of all three correct.According to the situation, calculation of given data are as follows,
Probability of all correct = [tex]\frac{a}{(a \times b )}[/tex]
By putting the value, we get,
Probability = [tex]\frac{3}{(3 \times 4) }[/tex]

Caroline was thinking of a number. Caroline adds 7 to it, then doubles it and gets an answer of 82.8. What was the original number?

Answer:
n = 34.4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Set Up
Let's let our number be set by variable n.
We add 7 to it: n + 7
We then double that entire expression: 2(n + 7)
That expression is equal to 82.8: 2(n + 7) = 82.8
Step 2: Solve for n
[Division Property of Equality] Divide 2 on both sides: n + 7 = 41.4[Subtraction Property of Equality] Subtract 7 on both sides: n = 34.4∴ Caroline's original number is 34.4.
